Core ECC bit invert vector (C0sd_cr_eccbitinv):
This vector operates individually for every ECC
bit in the selected 64b ECC block, during write
to DRAM. For all k between 0 and 7, when
bit(k) is set to 1, the value for the k ECC bit
(which corresponds with k data byte lane) is
inverted. Otherwise, the value for the k ECC bit
is not affected.
Core ECC Diagnostic Enable
(C0sd_cr_eccdiagen):
1: The ECC bit invert vector is used to invert
selected ECC bits, during writes to DRAM.
0: The diagnostic feature is turned off.
